CAUTION: read the following notes carefully before starting the
calibration procedure or bump test.
1. The gas detector CANNOT have any active alarms or faults during
calibration.
2.
For zero calibration of CO2 sensors, nitrogen (N2) is used as the
reference gas, while for the other sensors ambient air is suffi
cient.
However, in the latter case, make sure that the ambient air is free
of residual gas concentrations that the sensor is intended to detect
3. At altitudes above 2,000m, calibration will give a lower reading. In
these applications, the device must be calibrated for the specifi c
operating environment.
4. If using a variable fl ow regulator, adjust the gas fl ow-rate to
approximately 0.3 l/min.
5.
When starting calibration or a bump test, the device will automatically
go OFFLINE, and will remain so mode until the calibration procedure
or bump test is completed.
6.
For correct operation, always perform the zero calibration fi rst and
then the full-scale calibration. Performing these steps in the wrong
order will cause incorrect calibration.
7.
For correct operation, wait at least two hours after calibration before
operating the device, to ensure complete stabilisation.
8. The gases used for calibration must NOT be inhaled! Refer to the
corresponding safety data sheets. After use, the gas cylinders must
be discharged into a suitable exhaust hood or outdoors.

4.2.2 Zero calibration
MANUAL
1. Fit the plastic cap supplied in the calibration kit to the device and
connect the plastic tube to the calibration gas cylinder (or ambient
air, as described in the warning above).
2. Activate TACT#1 or MAG#1 for > 5 seconds. The LED will fl ash green-
green-red when the device is ready.
3.
Open the supply of calibration gas (or ambient air, as described
above).
4. Activate TACT#1 or MAG#1 within 30 seconds of step 1 to confi rm
the start of calibration. If not activated, the device will abort the
calibration procedure and return to normal operation.
5. The LED will start fl ashing in a green-red, green-red-red, green-red-
red-red sequence, until calibration is complete. To abort calibration,
activate TACT#1 or MAG#1 for > 5 seconds, shut off the gas fl ow
and remove the calibration kit. If calibration was successful (green
LED), go to step 6. If calibration failed (the LED fl ashes orange at a
frequency of 2 Hz), activate TACT#1 or MAG#1 once to cancel the
calibration procedure.
6. Stop the gas fl ow.
7.
Replace the gas for the zero calibration procedure with the gas for
full-scale calibration and continue the procedure.
RILEVA APP
1. Fit the plastic cap supplied in the calibration kit to the device and
connect the plastic tube to the calibration gas cylinder (or ambient
air, as described in the warning above).
2. Enter the Calibration section by selecting the corresponding button
in the Home tab. Then scan the barcode on the calibration gas
cylinder or manually enter the required information.
3.
Open the supply of calibration gas (or ambient air, as described
above).
4.
Select the “Start Zero” button to confi rm the start of calibration.
5.
A countdown then begins until calibration is complete. If calibration
was successful, go to step 6. If calibration failed, return to the Home
tab and press the Acknowledge button to clear the zero calibration
error.
6. Stop the gas fl ow.
7. Replace the gas for the zero calibration procedure with the gas for
full-scale calibration and continue the procedure.

4.2.3 Full-scale calibration
MANUAL
1.
Activate TACT#2 or MAG#2 for > 5 seconds. The LED will fl ash green-
green-orange when the device is ready.
2. Open the calibration gas supply (check that the concentration
indicated on the cylinder corresponds to the concentration declared
on the device label).
3. Activate TACT#2 or MAG#2 within 30 seconds of step 1 to confi rm
the start of calibration. If not activated, the device will abort the
calibration procedure and return to normal operation.
4.
The LED will start fl ashing in a green-orange, green-orange-
orange, green-orange-orange-orange sequence, until calibration
is complete. To abort calibration, activate TACT#2 or MAG#2 for >
5 seconds, shut off the gas fl ow and remove the calibration kit. If
calibration was successful (the LED will fl ash orange-green-red), go
to step 5. If calibration failed (the LED fl ashes orange at a frequency
of 2 Hz), activate TACT#2 or MAG#2 once to cancel the calibration
procedure.
5. Shut off the gas fl ow and remove the plastic cap from the calibration
kit.
6.
Wait for the device to stabilise completely, as indicated by the LED
on green steady.
RILEVA APP
1. Enter Calibration section by pressing the corresponding button in
the Home tab. Then scan the barcode on the calibration gas cylinder
or manually enter the required information.
2. Open the calibration gas supply (check that the concentration
indicated on the cylinder corresponds to the concentration declared
on the device label).
3.
Press the “Start off set” button to confi rm the start of calibration.
4. A countdown then begins until calibration is complete. If calibration
was successful, go to step 5. If calibration failed, return to the Home
tab and press the Acknowledge button to clear the full-scale
calibration error.
5. Shut off the gas fl ow and remove the plastic cap from the calibration
kit.
6. Wait for the device to stabilise completely, as indicated by the LED
on green steady.
CAUTION: do not use pure refrigerant or hydrocarbons (cigarette
lighter), so as to not excessively damage the semiconductor element,
which is sensitive to very high gas concentrations.
